Profile: APC International, Ltd. is a manufacturer and supplier of piezoelectric ceramics & piezoelectric products for customers in a wide range of industries including aerospace, automotive, consumer, engineering & design, industrial, manufacturing, medical products, and military. Our products include piezoelectric ceramics in standard & custom shapes, bending actuators, disc benders, ultrasonic cleaning components, ultrasonic air transducers, NDT components and ultrasonic welding components. In addition to our products, our skilled engineering staff and in-house research facilities enable us to offer a range of services, including materials development, systems optimization, custom joint development programs, transducer design & custom assembly. We supply piezo ceramic elements in a broad range of custom shapes, prepared from our lead zirconate titanate formulations, and carefully machined to tight tolerances. Our ultrasonic transducers consist of a piezoelectric ceramic element, mounted in an aluminum, plastic, or environmental (sealed) housing. These transducers offer high sensitivity, superb sound pressure level (SPL), and stable electrical and mechanical characteristics, at a choice of bandwidths. Environmental transducers may act as both transmitter and receiver; or separate transmitter or receiver. We can custom design air transducers for unique requirements.
